The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made themselves at home in the middle of the Sahara. Big thanks to Fabrizio De Rossi for the reconstructions of the Sahara past and present.

MLK's Final, Great Speech... delivered April 3, 1968 at Mason Temple in Memphis, Tennessee.

Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Come venture deep inside the world’s biggest physics machine, the Large Hadron Collider. This extraordinary feat of human engineering took 16 years and $10 billion to build, and just weeks ago began colliding particles at energies unseen since a fraction of a second after the big bang. We’ll explore this amazing apparatus that could soon reveal clues about nature’s fundamental laws and even the origin of the universe itself. John Hockenberry moderates a discussion among physicists including Marcela Carena, Monica Dunford, Jennifer Klay and Nobel laureate Frank Wilczek.
